Notizie su Indonesia e sui suoi vulcani :

L'Indonesia è il più grande arcipelago del Mondo composto da circa 13.677 isole di cui 3.000 abitate e solo una decina di grande estensione: Sumatra, Giava, Sulawesi (Celebes), Flores, Timor, Sumbawa, Seram, Sumba, Surabaya, Halmahera, Sud del Borneo, Est della Nuova Guinea. L'arcipelago si estende ad arco tra l'Oceano Indiano e l'Oceano Pacifico per 4.700 Km. da Singapore all'Australia sulla linea di frontiera tra Asia e Australia. La particolare posizione geografica dell'Indonesia ne ha influenzato la cultura e la vita economica, politica e sociale. L'Indonesia è la nazione che possiede nel proprio territorio il maggior numero di vulcani attivi al Mondo. Inoltre circa 75.000 anni fa è stata sede della più grande eruzione di tutti i tempi finora individuata: quella del lago Toba nel Nord dell'isola di Sumatra. 
L'Indonesia, predominantemente montagnosa, ha circa 400 vulcani, di cui circa 100 attivi, tra questi solo poco più di una ventina hanno manifestato una rilevante eruzione negli ultimi trenta anni. Ecco l'elenco dei vulcani indonesiani di recente attività eruttiva, suddiviso per regione. In Sumatra: Dempo, Merapi, Kerinci, Sorik Marapi, Peuet Sague; nello Stretto della Sonda: Anak Krakatau; in Giava: Bromo, Merapi, Raung, Semeru, Butak Petarangan; in Paluweh: Rokatenda, Galunggung, Slamet, Kelud; in Sulawesi: Lokon, Karangetang, Colo, Soputan; in Maluku: Dukono, Banda Api, Gamalama Kie Besi; in Flores: Lewotobi.

Caratteristiche del vulcano:

 Mount Peuet Sague is a complex volcano found in the province of Aceh, the northernmost province in Indonesia. It has had only one historical eruption, which began in 1918 and ended in 1921.Le mont Peuet Sague est un volcan complexe et et situé dans la province de Aceh, la province la plus au nord de l'Indonésie. Une éruption historique de Peuet Sague c'est produit en 1918 et se termina en 1921. The name Peuet Sague, which has numerous spelling variants (e.g. Peut Sagoe, Peuet Sagu, Puet Sagu, Peuet Sagoee), means "square." Accordingly, Peuet Sague, a stratovolcano, contains four summit peaks. It is located in Sigli Regency, Aceh Province near Seulawah Agam and Burni Telong volcanoes. The crater believed to be active resides SE of one of the peaks of the lava dome (Mount Tutung). This narrow crater has a diameter of about 70 m and a depth of 80 m.A May 1920 expedition was stopped by heavy ashfall and a 1952 expedition spent 20 days without reaching the volcano. A 1975 team reached the peak after nine days but found no eruptive activity. They documented a lake (500 x 800 m) at the foot of Mount Tutung containing water at a temperature of 19°C. Within Tutung's crater they found a small (40 x 75 m) blue lake with a temperature of 21°C. This intracrater lake was surrounded by four solfataras (with temperatures of 59-78°C).The last major eruption occurred in 1918-21 when ash was emitted, a lava dome was formed, and pyroclastic flows spilled into surrounding uninhabited forests. Scientists inspecting the summit area in 1984 found burned trees surrounding the main crater, likely due to a 1979 eruption. Local eye-witnesses and pilots reported ash columns above the summit in 1979, 1986, and 1991. An expedition in 1984 found burned trees surrounding the crater, attributed to the 1979 eruption. Uncertain activity was reported in 1949.

 

Peuet Sague 
On the 10th of January, the Vocanology Society of Indonesia (VSI) 
has reported that Peut Sague is one of most active 
volcanoes in Indonesia which is located in
Aceh with the summit at about 2780 m height. This 
strato volcano has exploded three times and contiues 
to explode into year 2001. The first explosion was in 25
December 2000 on 0800 (local time) and the second one was
at 1310. The third explosion was on 26 December at 1130.
The explosion produced ash volcanic
which caught a wide area, Geumpang village, Lutung,
Mane, Bangke, about 20 km to the summit; and Trans
SP.I, SP.III, SP.IV, SP.V which about 7 km to summit
of Peut Sague. From last information, Peut Sague produced
a lava flow which appeared at night from Trans village

produced lava flow which appear in night sight from Trans village. 

27 Aprile  1998 Peuet Sague erupted ash up to 1.8 miles (3 km) into the air on April 26. Another eruption of the volcano had occurred on April 19, but thick smoke from forest fires prevented observation of this eruption.
